11 claims. (o1. 14o- 93)V f This invention relates to an improved machine that has been devised for usein binding packing cases ofV all kinds and sizes with encircling bands of wire which, Vafter being passed round the case, are strained and have their ends secured by overlapping and twisting them together.

The machine provided by this invention embodies in it the known method of securing the overlapped ends of the wire band together, by the insertion thereof within ,av radial slot of a rotatable wheel member, so vthat' they occupy a position parallel with the members axis at about the centre of suchmember, in order that on rotation being imparted to such member, the overlapped ends are twisted-one onl the other.

This present machine, however, .is designed by its special features of construction, vto effect an improved tie for. securing the band ends together under which a more eiectiveolock between the ends is obtained than by merely over- With this class of machine. tie is effected by a method under which the wire band hasone ofl its yends doubled back on itself into a long open loop and the other end then brought to overlap the loop'so that there are three parallel strands ofwire, These three strands are then twisted together forja number of turns (the machine hereinafter described provides for three) so that an eiective non-slip grip is'exerted by one member upon the other.

larly described in the specification of my current application for United States Patent No. 590,589.

A further feature of this invention is that it will allow for the wire band being drawn from a coil of wire, and then after the band has been passed round the case and the tie effected,

may be drawn from the coil, one-by one, as each is placed and secured inY position upon its packgenerally hitherto prevailing with this class of band, of using previously cut band lengths. Consequently only enough wire is drawn from the coil to suit the length of band required for the particular size of casein each instance thereby preventing any `waste of wire.`

YThe* invention provides a machine designed to V.ing sheets of ldrawings, in vwhich:-

This set comprises a pinion 26, fixed on the operating spindle 24, an intermediate gear wheel 27 gearing therewith, and a second pinion 28 geared with the gear wheel. These are made of such ratio that on a fixed number of turns being imparted to the first pinion (three in the arrangement shown) 'the'intennedinte `vvl'ieel S27 willibe rotated'tlrrougha single rotation, While the seoond pinion 28 will rotate through the same .number of turns as the first pinion.

Upon the front of the sliding block 33 a clamp is provided such clamp being formed by a lower fixed jaw 43 projecting out from the block, and an upper eccentric jaw 44 xed upon a pivot pin 45 extending transversely through the block from back to front and which jaw is made with a handle 46 for closing it down on to the iixed jaw through the turning action thereof. The pivot pin 45 on which this jaw is fixed, is carried through the sliding block 33 and through a longitudinal slot 75 in the plate 22 of the frame, to the rear thereof to act in conjunction with release apparatus in a manner alsofhereinafter'described.-

, .At the extreme left of the base block 20 a transversely extending lever arm 47, shown in "enlarged detail in Figure 8, is mounted by pivoting -at---its rear end to the side ofV a vertical 'iiange plateV 48 upon the base block, so that its ifonwazrdfv'end may rise and fall, and this level` is spring cushioned as at 49 to normally raise l such :forward end. *This end is made with a 'forked vforward end and with an upwardly extending pin 50 in the lower member of the fork and the forward edge of the flange plate 48 iscut away `Witl'i'arecess -or Eslot5-1extendingrearwardly land the' said vrpin :projects upwardly' across ithe `:line of the 'bottom-of this recess and li'n Ithe iront -ffroma'medial position, "will'pass from the .line

This -slot 58 is Yfurnished with -vsteel dining plates 59 spaced apart -one -above'the other at about the thickness of vthe band wire.

The slotis made to extend inward for Ya lsuf- -inafter described'. The bending handle 53' at its extremity, `is formed with a llaterally projecting yiin 60 upon its inner -sider'and lthis handle is made of lsuch Ya length that when the handle is turned right in'across the vfront of themachine Ithe fin will enter vthe said'slot 58v 'andhold within it the wires that'maybe inserted'side by-side Iin Athe slot in the operations ofthevmachine y'handle v53 is also formed -near its end,

on its inner side withl-a pair of jaws 61 extending one above the otherlaterally from the handle. The upper jaw is formed onits top with a tooth 62.- Mountedon the base 20, in an appropriate position, is a pivoted pawl 63 v(shown more particularly in FigurelO) the forward endof which is provided with a tooth on its underside and normally drops downward to an extent limited by the rear ends engagement with the spindler32 of the gear wheel 27 and in such a position that when the handle 53 is turned'round, the tooth 62 engages beneath the pawl and lifts it so that it passes in beneath. The pawl then drops and engages the handle to retain it in such position against the action of its spring 56 tending to swing it back. A cam piece 64 is fixed upon the said spindle 32 to engage the rear end of thispawl, when the spindle is rotated, and to depress such end and raise the forward end to lfree the handles engagement with the pawl, so that the handle is position.

On the inner (or right hand) side of the frame plate 57 a vertioallymoving guillotine knife 65 (shown in Figure 11) is mounted and this is adapted to be Vdepressed by means of a cam lever 66 pivoted at 67, also on this face of the plate, and having a rear extension 68. Acam 69 is fixed on the end of the spindle 32 (which is carried through this plate) which in the turning of the spindle is adapted to engage the end 68 of the cam lever, raising it to depress the forward end 66 and thereby to depress the knife 65. Then as the cam Ypasses on, the lever is released allowing the forward end, and the knife, to be raised.

The knife is kept normally in a raised position by means of the bar 70 that is pivoted to extend longitudinally on the front of the plate 22 of the main frame and at one end to pass through the upper end of the knife frame 71 and then through a vertical slot 72 formed in the bearing plate 57 to receive it. A spring 73 positioned on the other side of the plate and shown in Figure l0, bears upwardly on the end of the bar to force it upward. This bar also extends for a distance, at 70a, on the other side of its pivot and the end of the pawl 42 engaging the slide block ratchet rack 4l (which pawl is arranged loosely on the same pivot) is made to overlie' this end and is kept pressed thereon by means of the ila-t spring 74 '(Figure 4) This provides that the pawl may spring upward to permit of the sliding block moving to the right, and then down,'to engage Vthe rack 41. It also provides that when the reverse end of the bar 70 is depressed to lower the knife, the pawlV 42 is lifted clear of the said rack, to free the sliding block and permit of it moving back to the left under the influence of its spring 34.V

The knife 65 is so made and so positioned with respect to the slot 58 that it passes down with a scissor out across the ends of the steel lining plates 59 thereof and at a distance out from the inner end of the slot sufficiently to clear a wire arranged at the inner end but to engage and cut through one upon its outside. This is shown in the detail Figure 14 of the drawings, where three side by side wires are shown heldin the slot by the iin 60 of the bending handle 53, the outmost wire not passing out beyond the cutting edge.

As previously mentioned, the pivot pin 45'of the clamping jaw 44 extends vthrough aY slot,

vvvhiohis shown as 75 in Figures 5 and 12 of vthe drawings, formed longitudinally in the vertical face plate 22 of the frame so that the slide v block 33 is left free to slide' to and fro. Onvthe rear end of this pivot pin there is affixed a lever arm 76 which extends radially and is bent so that it loosely connesbetwe'en its ends a collar 77 that is mounted to slide on a spindle 78 mounted longitudinally inVv the rear of the marchine.V This collar Vis provided with a lifting lever79 extending forwardly and underlying the said arm 76 in such a'manner that the turning -ofthe collar to lift the lever 79 up, will lift the the righthand side of such plate, is xed a lever 8O (Figure 11) which normallyfdrops downward to turn the lspindle to the position under which the `arm 76 of the clamp pivot 45 isfree to drop. This lever 80 is arranged in the course of rotation of thekcam 69 upon thespindle 32 so'thatas suchmoves upward in the rear portion of its travel, it willlift the lever a distance f Aand Vthen permit it to drop, before it passes on to engage and actuate the `cutting l.knife and pawl releasing l mechanism previously described.

These operations also are arranged to take place,

`relatively to the release of the bending handle 53,

-slot 51 'of the flange plate 48;- The extremity of the wire .is carried then to the ,point of thein 60 on the'bending handle which acts asa gauge to determine its proper adjustment. The wire is'then held by bending the handle 53 back to depress the pin vand cause the upper part of the lever 47:to clamp the wire on to the base plate. f a "L The main part Cfof the wire is then carried lroundtheY case and vbrought in across the maf lchine from left tol right, v being placed inthe front of the slot 51 and then along in theslot 30 of the pinion 28.and'through the slot 58,- and Y rtheninto the jaws of the clamp 43-44 to be *gripped ;thereby,;the sliding block being then V'positioned at the extreme left of its movement.

vThebending handle is then turned round on its pivot to bend the wire end A round the pin 150 into the open loop form B shown in Figure l and to place the outer member of this loop in the slot 30 of the pinion, 28 and in the slot 58. This bending is effected by the engagement of the bending arm 54 with the wire and in its wiping action aroundthe frontend of the flange 1 plate "48; the Wire being heldbetween the jaws 6l.V The handle then is .locked in Such position by engagement with the pawl 63 in themanner v described. Y

w The sliding block 33 is then actuated by the means provided, to move 'it to the right so that the mainwire isdrawn taut around the case and the block locked in the position required, by means of its holdinglpawl, theend ofthe wirerround thepin 50 will pro- The looping of v A .fit
